Steven Kim is an Australian-South Korean singer, dancer and member of LUMINOUS (루미너스). Before debuting, he spent 2 years and 8 months as a trainee under DS Entertainment (DS엔터테인먼트) and was set to debut in October 2019. However, after several delays and many internal problems, he decided to leave the company in August 2019 without debuting. He then moved to JYP Entertainment where he was part of the trainees trying to debut as STRAY KIDS.
After switching agencies to SE Group Entertainment (SE그룹 엔터테인먼트, formerly known as Barunson WIP), he made his debut in September 2021 as LUMINOUS's rapper and sub-vocalist with their first album, "Youth".
They have not released any new material since August 2022 but have been performing abroad since early 2023, as their international fanbase is bigger than their domestic one.
